lVlACi-hllixlE FOR SETTING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 309,625, dated December23, 1881i.

(No model.)

To @ZZ whom t may colzccrlm Be it known that I, ELEAZER Knnrsiemiyr., acitizen ci' the United States, residing at New Britain, in the county ofHartford and State of Connecticut, have invented anew and uscful Machinefor Fastening Buttons to Shoes and other Articles, of which thefollowing description and claims constitute the specification, and whichisillustrated by the accompanying ve sheets of drawings.

This machine operates with a treadle, and is used to attach buttons toshoes or other articles with the bntton-fastener and by the methoddescribed in my application for Letters Patent for an improvement inbuttoniasteners, iiled December 17, 1883.

In the drawings, Figure l is a plan view of that part of the machineabove the stand. Fig. 2 is a perpendicular crosssection on the line 7 7of Fig. l. Fig. 8 is a front view of the machine with the disk V andthat part of the stand forward ci the disk removed. Fig. i is aperpendicular cross-section on the line S S of Fig. l.. Fig. 5 is anedge view of the disk V. Fig. G is a view of the inner side of the diskV, with a portion ol' the ring broken away.

A is the stand. B is the treadle. C is the spring, lifting the treadleafter it is depressed by the foot of the operative. D is a jointedconnecting-rod, and E is a straight connecting-rod, both worked by thetreadlc. The connecting-rod E is attached to the treadle at F, so as tobe out ofthe way of the foot of the operative, and about twice as i'arfrom the pivot of the treadle as is the corresponding attachment of theconnecting-rod I).

G is a lever of the third order, the powerpoint of which is pivoted tothe jointed conl necting-rod D, and the fulcrum of which is pivoted tobrackets extending upward from the casting I-I, and the resistance-pointof which is the die that bends the prong of the buttoniastener, ashereinafter explained. The downward stroke of the die is limited by theend ofthe screw I, passing through the lever G.

.T and K are springs, the former of which is placed above the latter,and both fastened at their ,fixed ends to the upper surface ot' the N isa carriage reciprocating upon the right- 6o hand side of the bracket M,being attached thereto by the screw O, passing through the slot of thecarriage, and being operated by its indicated pivotal attachment to theconnecting-rod E. I is a pawl pivotcd to the inner side 0f the carriage,and worked by the spring Q, and limited in its outward movement by thepost R. S is a carriage reciprocating in the space between the forks ofthe bracket M. This carriage has a pla-in horizontal central round hole,and a plain perpendicular round hole of a much smaller diameterextending downward from the lower part of the periphery of thehorizontal hole through the lower wall of the carriage. The carriage issupported and reciproeated by the post T, the upper end oi whichprojects through the perpendicular hole and nearly half-way across thediameter of the horizontal hole oi the carriage S. The car- So riage:rests upon an annular shoulder on the post T, andY that post rests uponthe spiral spring l, which is inclosed in the lower part of the roundperpendicular recess in which the post T reciproeates.

V is a disk having a central round hole and a series of radial recesseson its inner side. In the bottom or" each ci' these recesses a fiatbifurcated spring, IV, is pivoted. Over the free ends of those springsthe ring X is screwed upon the border of the disk V.

Y is a lock-bolt having a milled disk for manipulation, and two annularshoulders ad jacent to that disk. The bolt proper is round and slightlysmaller in diameter than the hole 9 5 in the disk V and smaller than thehorizontal hole in the carriage S. The inner end ofthe bolt Y has arecess forthe reception oi the upper end of the post T. That recessstarts at .the end of the bolt and extends lengthwise along itsperiphery a little wider than the diameter.

thest side wall of the longitudinal part of the recess. That side ofthis lateral part of the recess which is nearest the smaller end of thebolt is slightly concave, with the axis of the concavity in thedirection of the diameter of the bolt.

Z is a spring cut from iiat metal and having a central hole,throughwhich it rests upon the larger of the two annular shoulders of the boltY, and also having extended corners bent toward the end of that bolt, soas to occupy a plane in advance of the plane of the smaller of the twoannular shoulders on the bolt.

A is the anvil, upon the upper concave edge of which the base of thebuttonfastener B is supported against the downward movement of the dieat the resistance-point of the lever G. The right-hand edge of the anvilA is shown in Fig. 2. ltisfastened by ascrew to the left-hand' end ofthe casting H, and has its upward projection extending parallel with butout of contact with that end of the casting.

The mode of operation of this machine is as follows: The bolt Y isremoved by giving a quarter-turn to the left and then withdrawing it.The disk V is then removed with the left hand of the operative, who withthe right hand places a single button-fastener between each of thesprings WV and the ring X in the position shown in Fig. 6. Then theoperative replaces the disk V, and the bolt Y locking the latter bygiving it a quarter-turn to the right, after it has been forcedinwardly,so that the longitudinal part of its recess incloses the top ofthe post T. Vhen the disk V is properly replaced, the upper projectionof the anvil A has its front side in contact with the front side of oneof the springs NV, which springs are sunk into their recesses so farthat their presented surfaces are as much below the general innersurface of the disk V as'the upper projection of the anvil is thick. Thedisk V being thus properly replaced, the operative with the left handholds the article to which the button is to be fastened between the diein the lever G and the upper part of the periphery of the disk V,and'between the springs J f and K, and with the right hand holds thebutton above the upper surface of the article to which it is to befastened and withl its eye Liiatwise under the die in the 1ever G. Theend of the lever G is concaved,

as shown in Fig. 1, andthe relation of the concavity to the position ofthe die is such that when the base of the button is held against theconcavity the eye of the button will bein the proper position forfastening. Then the operative with the foot depresses the treadle B. Theconnecting-rod D is thus forced to pull down the lever G,and the die endof that lever clasps the eye of the button between it andthe upperperiphery of the disk V, and then forces that disk bodily downward untilthe lower end of the screwv I comes in contact with the head of thescrew which holds the springs J and K. During this downward movement ofthe disk V the particular button-fastener which is just above theconcave upper edge of the anvil A is prevented by the anvil from goingdownward with the disk. The downward motion of the lever G thereforeforces the article to which the button is to be fastened down upon thepoint of the button-fastener, and also forces the eye of the button overthat point after the point has been forced to puncture the article towhich the button is to be attached. Thereupon the point of thebutton-fastener comes in contact with the concave die on the lowersurface of the resistance-point of the lever G, and by that die is bentover toward the longer end of the base of the button -fastener, and thenforced to penetrate into the upper surface of the article to which thebutton is being attached substantially as shown in the drawings of myaforesaid application for Letters Patent led December 17, 1883. Then theoperative releases the treadle B from downward pressure, and the treadleis forced to rise by the spring C. As it rises it forces the connect-ving-rodE and the carriageN upward, and with the carriage N the pawl Palso. In rising, the point of the vpawl engages with the upperrightlangled side of one of the recesses in the bottom of which one ofthe springs W is pivoted, andas it continuesto rise it forces the disk Vto revolve thirty. degrees upon its axis. The upward movement of thetreadle B also forces the connecting-rod D upward,

and that rod carries the lever G back to its original position,and thelever G, by releasing the disk V from downward pressure, allows thespring U to carry the disk upward to its original positionby means offorcing upward the post T, the carriage S, and the bolt`Y. Then theoperation above described as following the replacing of the disk isrepeated until the disk has made one revolution and the button-fastenersare all exhausted fromit. Then the bolt Y and the disk V are removed asbefore, and the disk is replenished with button-fasteners as before, andthe subscquently-described operation is repeated. Thus the work iscarried on for any length of time desired.

The speed of the machine may be doubled by using two specimens of thedisk V and employing two operatives, one of whom is supplying one of thedisks with fasteners while bination of the disk V, 'the lock-bolt Y, thethe other is using the other disk on the niacarriage S, the post T, andthe spring U, subchine in the described manner. i stantially asdescribed. 15
